Andy Burnham became Britain’s seventh prime minister in a decade yesterday, pledging to break with the politics of the past to deliver a new economic model to benefit a nation “fed up” with a revolving door of leaders. Starmer, who was ousted by his own lawmakers about a month ago, said his work as prime minister was “the privilege of my life” and that he wished Burnham every success. “He has my full support,” Starmer said. Burnham did not refer to Starmer in his speech, instead focusing on how he will rip up much of what went before. Beyond tackling homelessness, Burnham said he would build more public housing to help bring down welfare spending, which would help fund higher defence investment.
